Re: [PATCH 2/2] Add transport message for up-to-date references

Christopher Lindee [off-list ref] writes:

This raises a good point: if we default to the old behavior and only
send up-to-date refs when the new option is present (as is currently 
the case with this patchset), then existing scripts will continue to
work.  Moreover, scripts using the new option will consistently have
"up to date", so they can change the grep to use that (since it will 
never show "Everything up-to-date!").

Scripts should never be parsing the output meant for humans.  You
should worry about "git push --porcelain" output first.

I think we report "= srcref:dstref [up to date]" there and that is
what the scripts are expecting for an up-to-date case.  If you want
to allow the scripts to react to a forced no-op update differently
from the normal "we didn't even tell them about this ref" case, then
we'd need a different type letter or "[up to date]" string (or
both).
